Gluing established rock

[ThatPhillyReefer]

I am wanting to redo some of my aquascape. I want to take isolated rocks from my tank to make a Nsa structure. what do you think is the best type of bonding method for this?

Super glue, epoxy, e-marco mortar?
I also don’t want to leave the rocks out of the tank too long, but I do want a strong bond between the rocks.

I had good results bonding my rocks under water with Jurassic Gel (super glue gel available in a big ol tube at BRS). I setup my rockwork in the display and then glued it together several weeks later.

Be prepared though, you will probably only get one use out of the tube because if you suck ANY saltwater back in, the tube will harden completely as the saltwater causes it to cure.

Ive always used the two part (green and white) epoxy thats marketed at saltway tanks. I use it directly on the wet rock, sometimes even in the water lol
